Post-ERCP pancreatitis

Dr. NakaiYousuke Nakai, MD, PhD from the Department of Gastroenterology, Graduate School of Medicine at The University of Tokyo in Tokyo, Japan discusses his Original Article, “Risk factors for post-ERCP pancreatitis in wire-guided cannulation for therapeutic biliary ERCP.”

This study was an analysis of risk factors for post-ERCP pancreatitis (PEP) in wire-guided cannulation (WGC) for therapeutic biliary ERCP .

WGC has been shown to reduce PEP by avoiding pancreatogram, but it is not clear whether incidental guidewire insertion into the pancreatic duct (PD) can increase the risk of PEP or not.

Our analysis revealed 2 risk factors for PEP: guidewire insertion into PD and a small bile duct. Even a single guidewire insertion into PD can increase the risk of PEP, especially in patients with a small bile duct. The role of prophylactic PD stent placement right after a single guidewire insertion should be further investigated in a prospective randomized controlled trial.
